Example 1: Two different enzymes are able to catalyze the same reaction, A → B. They both have the same Vmax, but differ their K

luda_lava [24]

Answer: (a) = 0.022mmoles/minute; (b) = 0.00022mmoles/minute; (c) = 0.022mmoles/minute

Explanation:

The Michaelis- Menten equation is used to show the relationship between substrate concentration and reaction rate.

The equation is Vo = Vmax[S]/(Km + [S]

where Vo is the initial velocity, Vmax is the maximum velocity, [S] is the substrate concentration, Km is the Michaelis constant.

(a) For enzyme 1; Vo = 0.002mmoles/minute, Vmax = ?, [S] = 0.1mM, Km =1.0mM; making Vmax subject of the formula;

Vmax = Vo * (Km + [S])/ [S]

Vmax = 0.002*(1.0 + 0.1)/ 0.1

Vmax = 0.022mmoles/minute (Vmax for Enzyme 1&2)

(b) Vo = Vmax[S]/(Km + [S]

Vo = 0.022 * 0.1/(10+0.1) = 0.00022mmoles/minute

(c) Vo = Vmax[S]/(Km + [S]

Vo = 0.022*1000/(1.0+1000) = 0.022mmoles/minute

The snapping turtle shown above, lives in a small farm pond, where its major prey is largemouth bass. In turn, the bass primaril

LUCKY_DIMON [66]

One snapping turtle weighs 40 pounds, so 10 snapping turtles in a pond have a total weight of 400 pounds. The turtles eat largemouth bass (1 trophic level below them), and the bass in turn eat minnows (2 trophic levels below the turtles). So since only 10% of energy is passed in each trophic level, we would need:
(x lbs of minnows)(10%)(10%) = 400 lbs of snapping turtles
x = 40000 lbs of minnows (Choice C)

Lab stations activity: investigating complex inheritance patterns

Andrei [34K]

Answer:

Mendel's laws only apply to some restricted hereditary situations, that is, to those traits that are determined by a single pair of allele genes and that are found on different homologous chromosomes. Among the hereditary mechanisms that do not conform to the laws described by Mendel, the complex inheritance patterns can be mentioned: intermediate inheritance, codominance, multiple alleles and inheritance linked to sex.

Explanation:

Inheritance has patterns of transmission from parents to children such as those governed by Mendel's laws known as Mendelian inheritance, however, there are other inherited patterns known as complex inheritance patterns, among which are intermediate inheritance, codominance, multiple alleles and inheritance linked to sex. An inherited trait with an intermediate inheritance pattern expresses the two alleles that the individual possesses, but neither of them is observed as it originally is, but rather an intermediate phenotype is seen. Codominance is a situation that occurs when two different alleles are found in the genotype and both are expressed. Multiple alleles or polyalelia occur when genes have more than two allelic forms. In the case of multiple alleles, three or more alleles are present to determine a population trait. Sex-linked inheritance refers to the transmission and expression, in different sexes, of genes that are found in the non-homologous (heterologous) sector of the X chromosome inherited from the father. Two known examples are: hemophilia and color blindness determined by recessive genes in both cases.
